Hi list, Under a window system, Emacs frames want to be resized in certain increments. The window manager usually respects this, so an Emacs frame is usually w * W pixels wide and h * H pixels tall, where w and h are integers and W and H represent the character width and height, respectively.
This usually results in each Emacs frame displaying a whole number of lines of text. But I've got my `mode-line' face set to make it draw a two-pixel border around the mode line. This means that my Emacs frames are not displaying a whole number of lines of text. Assuming plain-text buffers, I always see only part of the bottom-most line of the bottom-most window of each frame. This in itself doesn't bother me. What does bother me is what happens when Emacs is forced to be a certain height. If an Emacs frame that is displaying a partial line immediately above the mode line is forced to be a single pixel taller, that one pixel goes to waste. This screenshot demonstrates the phenomenon: <http://www.brockman.se/software/emacs/dead-space.png> Notice the dead space at the very bottom of the frame. Those ca. 10 pixels could be put to better use by extending the main window height by 10 pixels, so that the dead space would be eliminated. The same thing happens for the frame width (in the above screenshot, I believe there are two pixels of dead space to the far right), but that doesn't bother me as much. You can reproduce this easily by bringing up a buffer with large headings, such as the Info system, and then maximizing the Emacs frame in, e.g., GNOME. Unless you are very lucky and the pixels add up just right, you should be able to observe the partial line and dead space. I have been strolling through the source code trying to figure out how difficult this would be to fix, but I'm not sufficiently familiar with the code so I have to give up. I'd appreciate it if someone who knows this code better could evaluate the difficulty of fixing the problem. Please let me know if any part of the problem is unclear.
